I need to find an electrician for a few miscellaneous things at my house tomorrow. Is there a site where you can post a job and have local electricians say if they're available an give an estimate?
You should post your location.
In Ontario make sure they have an electrical contractors license. Handymen are not permitted to do electrical work.
If you want a list go here and click "directory". You will get list of all the licenses in your area.
